The Blackhawks were desperate to get their offense going, so head coach Joel Quenneville put Patrick Kane and Jonathan Toews together on his top line. The reunion worked as Chicago built up a 3-1 lead midway through the second period. (Game 4 was the first time Kane and Toews both scored in a playoff game since April 2010.) Then things got crazy.

In the extra frame, the Bruins were unable to clear the puck from their zone when Seabrook picked it up and fired it past Tuukka Rask.

"It's one of those things that we talked about all year, all playoffs is getting pucks to the net," Seabrook told NBC Sports afterward. "It just sort of found a way in."

The series now shifts back to Chicago for Game 5 on Saturday night and with the Blackhawks having re-discovered their offense and successfully scoring on a power play after firing blanks on 11 opportunities entering Wednesday night.

After the offensive struggles in their two losses, the Kane/Toews combination paid off in Game 4, making one wonder why they weren't put together before earlier.

"You always get second guessed," said Quenneville. "There's reasons why. At the same time, you know, I think we didn't mind the way we played the first game, first part of the second game. Game 3 we were disappointed with our offense. So we went to the well."
